Removing the space from top of form

Yes, i have seen all the different ways to do this on the forum, but none seem to be working. what am I missing? I did it using the joomla way, and the regular way.

thanks

Please inject this custom CSS code to remove all the white space above the form:

.form-all {
padding-top: 0px !important;
}

#id_15 {
margin-top: 0px !important;
padding-top: 0px !important;
}

Here's a guide on How-to-Inject-Custom-CSS-Codes. Here's the result:

Hope that helps. Thank you.
